SELF's April cover girl Kim Kardashian confesses that she never really identified with models. "Growing up, I saw only skinny models and didn't relate," she says, admitting that she has a "big butt" (though many of us would die for her curves).

The jaw-droppingly gorgeous star of Keeping Up with the Kardashians and Kourtney and Kim Take New York says she is “curvy and proud,” but she still struggles with “insecure moments.”

“I love to eat! Especially sweets. And I’ll say it, I think my thighs are jiggly and I have cellulite,” she reveals.

But Kardashian, 30, says she doesn’t let her body woes get in the way of her workouts.

“Because when I put the time in at the gym, I’m confident. You have to feel good to look good.”

Atta girl!

Kardashian is not the only star who refuses to let her “imperfections” get her down. Read on to see how Minka Kelly, Rihanna and Megan Fox battle the body blues.

“The scar from the appendectomy I had when I was little and the one from the boogie boarding accident I had a few years ago make me unique, and I’m proud of them,” Kelly, 30, tells SELF.

“That said, there are days when I have less confidence than other days. When that happens, I try to treat myself the same way I would treat my best friend — meaning, I love my friends for who they are and don’t focus on their ‘flaws.’ So I try to do that for myself, too.”

“I realized that I actually like my body, even if it’s not perfect according to the book,” the sexy pop star tells the new issue of Vogue. “I just feel sexy. For the first time, I don’t want to get rid of the curves. I just want to tone it up. My body is comfortable, and it’s not unhealthy, so I’m going to rock with it.”

Rihanna, if we were you, we wouldn’t change a thing!

Megan Fox

Megan Fox also struggles with her body image — but she’s worried about looking too skinny!

“She gets frustrated at times because she’s like ‘I need to put on weight.’ So she actually weight-trains to keep on that lean muscle tissue,” her trainer, Harley Pasternak, told HollywoodLife.com.

So there you have it — even skinny girls get the body blues. How do you handle those not-so-perfect days?
